Cantharellus cibarius''), the Pacific golden chanterelle (''

The family was originally described in 1888 by German
mycologist
Mycology is the branch of biology concerned with the study of fungi, including their taxonomy, genetics, biochemical properties, and use by humans. Fungi can be a source of tinder, food, traditional medicine, as well as entheogens, poison, and ...

Joseph Schröter (14 March 1837 – 12 December 1894) was a German mycologist and medical doctor. He wrote several books and texts, and discovered and described many species of flora and fungi. He also spent around fifteen years, from 1871 to 1886 ...

Economic importance
Many species of ''Cantharellus'', ''Craterellus'', and ''

edible and several are collected and marketed on a commercial scale. In Europe, the commercial species are ''
Cantharellus cibarius'', ''
Craterellus cornucopioides'', and ''
Craterellus tubaeformis'' which are sold fresh, dried, or canned and are either sourced in Europe or imported, mainly from China.

In North America, ''

The global trade in species of the Cantharellaceae has been estimated (2005) to be worth over £1bn (US$1.5bn) per year.
